Dear Laurent,

Thanks for your guidance .

I have a question . If I want to run demos in situation that I am installed CGAL from software center and  by use of Install the package named "libcgal-dev". what can I do for run demos and example ?

when I install the package named "libcgal-dev" I have a folder named CGAL in "file system/usr/bin/CGAL" and also I have some .so file in

"file system/usr/lib".

but it seems I have not any demo or example and source .cpp file of CGAL . what can I do for run demos and example ?.

2- If I decide to run CGAL from source in ubuntu linux I should install all dependencies package you have listed one by one ?

Thanks alot for your help.

Install the package named "libcgal-dev". It will install a lot of dependencies
of CGAL:

libboost-dev
    Boost C++ Libraries development files (default version)

libboost-graph-dev
    generic graph components and algorithms in C++ (default version)

libboost-program-options-dev
    program options library for C++ (default version)

libboost-thread-dev
    portable C++ multi-threading (default version)

libgmp3-dev
    Multiprecision arithmetic library developers tools

libmpfr-dev
    multiple precision floating-point computation developers tools

libqt3-mt-dev
    Qt development files (Threaded)

libqt4-dev
    Qt 4 development files

zlib1g-dev
    compression library - development

Source: http://packages.ubuntu.com/lucid/libcgal-dev

After you have installed libcgal-dev, if you want to compile it from sources,
remove the packages libcgal and libcgal-dev from your system, and compile from
CGAL sources. All the main dependencies of CGAL should remain installed.
